CLEANING OR POLISHING MACHINE.

SPECIFICATION formingpart of Letters Patent No. 670,856, dated March 26, 1901.

Application filed January 12, 1900- $erial No. 1,211. (No model.)

To all whom, it may concern:

Be it known that we, CHRISTIAN F. DILG and CHARLES H. J. DILG,citizens of the United States, residing at New York, in the county and State of New York, have invented a certain new and useful Cleaning or Polishing Machine, of which the following is a specification.

Our invention relates to portable cutlery cleaning and polishing machines; and it has for its object the provision of an appliance of the kind set forth, simple in construction, inexpensive to manufacture, and which operates smoothly and efficiently in practical use.

To attain the desired end, this our invention consists in the construction, arrangement, and operation of parts herein set forth.

In the drawings which accompany and form a part of this specification, Figure 1 represents a plan View, with the cover partly broken away, of a machine constructed according to our invention. Fig. 2 is a plan view of the bottom of the same. Fig. 3 is a side elevation of the same, and Fig. 4; is a plan View of another machine constructed according to our invention.

Like letters of reference indicate like parts in all the views.

WVe have found it desirable to make a machine that may be used in the household and which can be readily carried around and that may also be clamped to a table, shelf, or other projecting part, and by means of which the insertion of the knife between the rolls may be facilitated, and We have therefore constructed according to our invention an organization of the class described embodying the preferred construction of parts and their mutual relationship, combination, arrangement, and organization in a composite body or structure, as hereinafter described.

Referring particularly to the drawings, A denotes the base-plate of our machine provided with suitable securing means, as the clamp a. Vertical posts B, provided with obliquely-located bearings B and arms 1), rise from the base A and serve to support the axes D of the rolls E and the horizontal driving-shaft C. The shaft 0 and axes D are respectively provided with skew-bevel gearwheels 0 D, which mesh with each other, and the rolls E are held together in an ad justable relation by means of the steel friction-disks b and adjusting-screws b, located in the bearings B.

Our rolls E are provided with an abradingfacing of elastic or flexible material. A post G, secured in this instance, serves to support an adjustable rest 6, preferably constructed of brass or copper and adjustably supported by means of a set-screw g. A crank-arm I-I serves as a handle to turn the shaft 0, and the gears O D may be covered with a hood J, as in Fig. 1.

We sometimes use in connection with our machine a buff or brush or grinding-wheel K, mounted on an axis and rotated by the engagement with its gear 7c of the gear D The axis 70 preferably works in a bearing K, connected with the bearing B by the arm k In lieu of using one straight shaft 0 we sometimes make our machine with two driving-shafts C parallel with the axes D, as shown in Fig. 4, in which case the said axes D are provided with straight gears D, which mesh with gear-wheels O of the shafts 0 which are supported by posts 12 The inner ends of the shafts O are provided with bevel gear-wheels C, which mesh with each other, and the whole mechanism is operated by the crank arm or handle H It is manifest that various omissions of some particulars could be made without materially affecting the essential features of our invention or the operation of the remaining parts, and we do not therefore wish to be limited to the specific structural details of the organization set forth. Obviously the elements of the structure described may be located at an angle to the plane in which they are shown. We accordingly use the words horizontal, vertical, and the like in a relative sense.

In operation after our machine is fastened to a table or other suitable support the knives, 850., to be cleaned may be placed within and drawn between the rolls. On acin line with each other.

' dust, &c., falling from the cleaning-rolls,

which dust drops through the orifices m,which constitute the open bottom of our machine. It will be observed that our gear-wheels are located at such a height from the bottom of our machine that even if there is an accumulation of powder or dust the said gears will never become clogged up or caused to be ground away by the abrading-powder.

As it is evident that many changes in the construction and relative arrangement of parts might be resorted to without departing from the spirit and scope of our invention, we would have it understood that we do not restrict ourselves to the particular construction and arrangement of parts shown and described, but that such changes and equivalents may be substituted therefor, and that What we claim as our invention is 1. The combination, with a cleaning or polishing truncated-shaped roll provided with an abrading-facing of elastic or flexible material, to provide yielding means, and having a double face, namely, a flat face and an inclined or conical abrading edge, of another similar roll, a knife-rest located below the axes of the rolls, and adjusting means for the same and for the two rolls, to hold the adjusted rolls against lateral movement, the axes of said rolls being obliquely disposed as regards each other in such a manner that the said conical edges of the two rolls will, at all times, register in a straight line, or parallel lines, according to whether'they contact or are separated, directly above the rest, and

the distance between the top portions of said edges will always be the same as that between the bottom parts of the same, whereby an article drawn between the rolls may be treated with an equal friction or pressure at all points of said yielding, elastic conical faces, in the plane of the article to be cleaned.

2. The combination, with a frame or base,

of a cleaning or polishing truncated-shaped roll provided with an abrading-facing of elastic or flexible material, to provide yielding means, and having a double face, namely, a fiat face and an inclined or conical abrading edge, of another similar roll, a knife-rest located below the axes of the rolls, and adj usting means for the same and for the two rolls, to hold the adjusted rolls against lateral movement, the axes of the said rolls being obliquely disposed as regards each other in such a manner that the said conical edges of the two rolls will, at all times, register in astraight line, or parallel lines, according to whether they contact or are separated, directly above the rest, and the distance between the top portions of said edges will always be the same as that between the bottom parts of the same, whereby an article drawn between the rolls may be treated with an equal friction or pressure at all points of said yielding,'elastic conical faces, in the plane of the article to be cleaned, the driving gear-wheels being located above the lower peripheral line of the said rolls, to prevent the cleaning powder or dust, carried on the periphery of said rolls from clogging up the said gear-wheels.

In testimony of the foregoing specification we do hereby sign the same, in the city of New York, county and State of New York, this 26th day of December, A. D. 1899.
